Hiroki Narimiya (not ringing any bells?), while antagonistic attorney Miles Edgeworth will be played by Takumi Saito. Phoenix's charmingly naive assistant, Maya Fey, will be channeled by Mirei Kiritani.
Of course, you'll probably recognize the director (as reported earlier): Takashi Miike of Audition, Crows Zero and -- most recently -- Thirteen Assassins.
If you find the idea of a live-action, comedic courtroom adventure odd, you must not have been around for the Phoenix Wright musical a couple years back.
